TYPE-CASTING MOLD.

SPECIFICATION forming part of Letters Patent No. 405,419, dated June 18,1889 Application filed September 7, 1888- Scrial No. 284,792. (N0model.)

To all whom it may concern.-

Be it known that I, HENRY KLEMM, a subject of the Emperor of Germany,residing at arefully set forth in the following specification, referencebeing had to the accompanying drawings, forming a part thereof.

This invention relates to devices for easting inortised type and freeingthem from the mold. The drawings represent the familiar form of moldwith my improvements embodied therein.

Figure l is aplan, the up per member of the mold being broken away,showing the lower member in an ordinary position. Fig. 2 is a similarplan showing the parts in the position caused by the opening of themold, and showing the type just ejected. Fig. 3 is a side elevation ofthe mold in the same position shown in Fig. 2, but showing the uppermember of the mold also and being partly sectional to show the featurespertaining to myinvention,

section being made at 3 3 on Fig. 2. Fig. at

is a detail plan of the lower mold with the parts above the bottom plateof the body removed and showing a modified form of the type-ej ectingarm.

A is the base-frame.

A A are brackets to the end of which the arm B, which carries the upperend of the mold, is pivoted in the usual manner.

0 is the back plate of the lower member of the mold.

D is the carriage.

M is the jetrblock pertaining to the lower member of the mold.

N is'the type.

For convenience of reference, the side of the mold on which thejet-block is located will be called the jet side, and the opposite sideat which the face of the type is formed will be The body comprises thebottom plate E, the top plate E and the core E gwhich are securedtogether and to the carriage D in the usual manner. To the rear end ofthe back plate 0 there is secured the bracket F, on the upper end ofwhich the plate G rests, being kept in position and guided in the motionhereinafter described by the bolt H, which passes down through the slotg in said plate and is screwed into the bracket F.

To the rear edge of the plate G on the under the armI extending in theplane of the lower plate E of the body, said plate being cut away on theface side to allow the finger c' of the arm I to extend through or pastit to its for ward edge. The arm J is provided with the finger 7 at theforward end, which extends through the j et-block to the forward edge orface of the same. To the block B, in which the arm B which carries theupper member 13 of the mold is secured, there is pivoted the arm P onthe face side. The bolt 19, which forms the pivot, is arranged to bindthe arm P quite firmly against the block, so that the arm will not turnreadily upon its pivot, but will stand in whatever position it may beplaced about the same. The forward end of the arm P, when the said armis turned on its pivot to the position shown in Fig. 3, abuts againstthe arm K. To the bed A there is secured the spring L,which stands up infront of the arm K and tends to resist forward movement of the said armand the parts connected with it, and to retract them after suchmovement. The arm P is provided with the handle P ,which projects outpast the bracket A and is in convenient position to be grasped to swingthe arm P out of position for en gaging the arm K.

The operation of this device is as follows: The type having been cast inthe usual manner, the core E projecting into and forming the mortise nin the type, when the mold is opened for the purpose of permittin g thetype to be discharged, the arm P, standing 1n position to collide withthe arm K, engages that arm as the upper member of the mold swings up,the forward end 1) of the arm P moving forward as the upper member ofthe mold rises, and in that motion sliding the plate G and both of thearms I and J forward. The arm I, by means of its finger 7;, pushes outthe type at the face end by its engagement with the edge of the lowerwing n of the type below the mortise a, while the arm J by its finger jpushes out the jet end of the type by its engagement behind the jet N.The position of the pivot 19 of the arm P with respect to the pivot b ofthe upper member of the mold is calculated so that the motion which themold has in opening is sufficient to move the parts I and J forward adistance as much as the projection of the core E that is to say, thedepth of the mortise nso that when the mold is opened fully the type isfully relieved from the core.

Obviously the arm I may be of any width at the end of its finger i,where it impinges on the type to eject it, and it might be constructed,as illustrated in Fig. 4, so that the entire forward edge of the lowerplate E of the body should be constituted of the movable partcorresponding to the arm I and its finger i, and in that case it wouldbe preferable also to follow the construction shown in said figure byproviding two branches I I, joined at the forward end by the portionwhich constitutes the forward edge of the bot tom plate, one arm passingeach side of the screws which bind the parts of the body together, andbeing fastened to the plate G, one on each side of the bolt H. In casesuch structure is adopted, the arm J may be dispensed with and the typeejected or relieved from the core solely by means of the part I. In theform illustrated in Figs. 1, 2, and 3 I find it desirable to limit theretraction of the fingers c' and j, so that their ends shall be,respectively in the plane of the forward edge of the lower plat-e E andthe plane of the vertical face of the jet when the type is being cast;and this I accomplish by making the recess e in the lower plate, andproviding the finger t with the tooth z" projecting into that recess andhaving all necessary play longitudinally therein, the recess and tooth,however, being so located that when the rear edge of the tooth z" isstopped against the rear end of the recess e the forward ends of thefingerz' is flush with the forward edge of the plate E, and the end ofthe finger j is flush with the vertical face of the j et-block.

When it is desired to open the mold by throwing the upper memberentirely over, or for any purpose to throw it farther over than it couldbe opened when the arm P was in position to engage the arm K, said arm'may be thrown up to the dotted position shown in Fig. 3, when it willnot impede the opening of the mold.

I claim 1. In a mold for casting type, in combination with the fixedmember of the mold, and a bar reciprocating therein having its forwardend constituting part of the type-body-forming face of the mold, an armactuated by the arm which carries the oscillating member of the mold andactuating said reciprocating bar, substantially as and for the purposeset forth.

2. In a mold for casting :type, in combination with the fixed member ofthe mold, and a bar reciprocating therein having its forward endconstituting part of the type-bodyforming face of the mold, an armactuated by the arm which carries the oscillating member of the mold andactuating said reciprocating bar, and a spring reacting against the barto resist its forward thrust, substantially as set forth.

3. In a mold for casting type, in combination with the fixed member ofthe mold, and a bar reciprocating therein having its forward endconstituting part of the type-body-forming face of the mold, an armconnected to the arm which carries the oscillating member of the moldand engaging the reciprocating bar, the connection of said arm to theoscillating member being such as to permit mot-ion of the arm thereat,whereby itmay be moved aside at will to prevent its engagement with thereciprocating bar, substantially as set forth.

4. In a mold for casting mortised type, in combination with the carriageand body secured thereon having a fixed core, and a reciprocating barunderneath the core having its forward end constituting part of thetypebody-forming face of the mold, an arm actuated by the arm whichcarries the upper member of the mold and actuating the reciprocatingbar, and a spring reacting against the bar to resist its forward thrust,substantially as and for the purpose set forth.

5. In combination with the carriage and the body having the fixed core,the reciprocating bars I and J, the former lying underneath the core,the latter projecting through the vertical wall of the j et-block, saidreciprocating bars being rigidly united at the rear end, and alaterally-projecting arm K, rigid with them both, the arm P, actuated bythe arm which carries the upper member of the mold and contacting thearm K, and a spring L, reacting against said arm on the opposite sidefrom the contact of the lever P, substantially as and for the purposeset forth.

In testimony whereof I hereunto set my hand, in the presence of twowitnesses, at Chicago this 30th day of August, 1888.
